The clinical and multimodal imaging characteristics of paracentral acute middle maculopathy / 中华眼底病杂志

Objective To observe the clinical and multimodel imaging characteristics ofparacentral acute middle maculopathy (PAMM).Methods Retrospective case series study.From January 2014 to August 2018,12 eyes of 12 patients with PAMM diagnosed in Department of Ophthalmology,Peking University People's Hospital,were included in this study.There were 9 males and 3 females,with the mean age of 57 years.All patients were referred for sudden impaired vision,with or without paracentral scotoma.The patients underwent BCVA,slit lamp examination,fundus photography,FFA and OCT.Simultaneously,OCT angiography (OCTA) was performed in 10 eyes,visual field was performed in 5 eyes,near infrared fundus photography was performed in 1 eye.Clinical and multimodal imaging findings were reviewed and analyzed.Results Among 12 eyes,there were 5 eyes with BCVA 0.05-≤0.1,4 eyes with BCVA 0.3-0.5,3 eyes with BCVA 0.6-1.0.There were 1 eye with central rentinal artery obstruction (CRAO),7 eyes with branch retinal artery obstruction (BRAO).Among them,BRAO with central retinal vein occlusion (CRVO) in 1 eye,with non-arteritic anterior ischemic optic neuropathy in 1 eye,with diabetic retinopathy in 1 eye;old BRAO in 3 eyes;pure BRAO in 1 eye.There were 4 eyes with pure CRVO,including 3 eyes with ischemic CRVO.All eyes demonstrated hyperreflective lesions at the level of the inner nuclear layer and/or outer plexus layer on OCT.En face OCT highlighted the areas with hyperreflectivity corresponding to these lesions.OCTA demonstrated significant deep capillary dropout,abnormal morphology and enlargement of foveal avascular zone.Conclusion Hyperreflective band-like lesions at the level of the inner nuclear layer on OCT and middle retinal perivascular hyperreflectivity on en face scan are characteristic in PAMM.

ESTIMATION OF THE FEMALE NOSE TIP POSITION OF THE HAN NATION ALITY IN NORTHEAST CHINA / 中国法医学杂志

The relationship of the nose tip position and the skull figures which were measured from the lateral craniographs in 49 ladies of 17～19 age living in Shenyang was studied. The figures measured on craniographs were analyzed by multiple stepwise regression analysis on IBM-PC/XT computer, and the regressoin equations for estimating the nose tip position of female in Shenyang were obtained. Cases in which the errors were within 2 mm were 71.43 to 77. 55 percent.
